คุณลักษณะ

• Since the surface of the screw is machined by cold rolling, the hardness of the surface of the screw surface is improved by work hardening, and the fiber structure of the metal is not cut, so the mechanical properties are also superior compared to the worm of machine cutting.
• The surface hardness after rolling is 1.2 to 1.3 times greater than the hardness of the base metal, resulting in a "screw surface hardness of HB240~ 260."
• Since the surface roughness of the threaded surface of the rolling worm is mirror, the life of the worm gear is longer when used in combination with a worm wheel than when combined with a worm that has been cut.
• Used for general industrial machinery, medical equipment, food machinery, etc.
